The suspect is a former employee of Grady Crawford Construction Co. and the victims were all company employees, according to Casey Rayborn Hicks, a spokeswoman for the East Baton Rouge Parish Sheriff's Office.

A company foreman tackled and disarmed him before sheriff's deputies arrived, Hicks said.

Two of the victims were pronounced dead at the scene, while the third was taken to a hospital with injuries that were considered life-threatening, Hicks said. She wouldn't identify the suspect and said the victims' identities were being withheld pending notification of relatives.

"It's still a very fluid situation," Hicks said.

Michael Crawford, wife of company co-owner Grady Crawford, said she didn't know the identities of the alleged gunman or victims and was waiting to learn more about the incident from her husband.
